I've been meaning to make a post about this for a while - but just for those that are interested in these cars, I've just kept a bit of a running log.

At the moment I'm running it alongside my C63 but I'm probably looking to sell the C63 in the next couple months as I just fancy something a bit cheaper and that I can worry less about. I've always fancied a 130i and there is little I could find for something which has a decent engine, decent interior, some decent "tech" (albeit a bit older), rear driven and is fairly cheap and cheerful to run. I finally found a fairly decent example online and managed to get it for £4250. It's a 2007 LCI LE with 153k miles on the clock, FSH, Bi-xenons, full electric memory leather, i-Drive, brand new Goodyear Eagle F1 Asymmetric 5 tyres all round. It came with crazy amounts of service history and repair receipts from a BMW specialist and with only 2 previous owners. Last owner alone spent £3k on it a couple of thousand miles ago putting in front and rear M3 control arms, Bilstein B14 coilovers, full service including diff/gearbox etc etc and from before that, judging by the invoices it's always had everything it's needed without money seemingly an option!

It's needed a few bits doing on it since I bought it, but I managed to get the price down quite a lot to account for this. These cars really aren't that difficult to work on, and after working on the C63 and E92 M3 - it's such a revelation to have space in an engine bay to allow you to work without having to do everything with your fingertips (even though this is the smallest car in the range and has a 6cyl 3litre engine!).

Anyway, this thread was just going to be a bit of a running log of bits and pieces that I've done. I've done a few bits already, so I'll put them up

First things first, this is what she looks like:

First things first, when I bought it I could see that the oil cooler and the oil filter housing gasket was leaking, so I set about changing that. I used OEM Elring parts and I think for both gaskets it was around £20. Took around 2-3 hours when i was taking my time and cleaning things up along the way. This job was one that needed doing promptly, as the oil filter housing sits right above the auxillary belt and if oil leaks onto the belt, it can cause the belt to snap and the belt somehow can get ingested into the crank seal, which is not good! I had a few other bits to do whilst I was in that area so I got them done at the same time, including new belt, pulleys and tensioners. Managed to get the belt/pulleys/tensioners for around £50 - again all OEM high quality SKF parts

I also decided to change the "mickey mouse flange". This is a coolant pipe with a flange which connects into the oil filter housing and which is made of plastic from factory. This plastic flange frequently gets very brittle, cracks up and causing a coolant leak and pieces of plastic to go into the cooling system where it can cause blockages or damage to the water pump. For like £10 on Amazon they make an aluminium one which fits perfectly and will never need to be changed again so it's a no brainer. The old plastic one is secured to the coolant hose with a one time clamp so the best way of getting it off, is just by crushing the plastic flange with some water pump pliers, then pulling it out, removing the one time clamp and replacing it with a jubilee clip and the aluminium flange. Needless to say, it was very brittle.

Great alloys and makes a change from the common ones that appeared on the 1 of that era.

Yeh definitely, really like the LE alloys. The alloys were in a bit of a state when I got it though (forgot to take photos though!) - all four were completely curbed and they had brake dust staining on that simply wouldn't budge. A refurb was the only option which I got done a couple of weeks ago. Cost me £230 all in for them to be powdercoated and they look so good now. The centre wheel badges were completely messed up also (they were the factory ones) so I got some new ones of those. I paid about £9 for 4 replica ones (not paying BMW prices for these which I think are about £50 for 4 these days!). I've bought replica ones before and was blown away by how good they look a feel which makes buying the BMW ones pointless.

Then I realised that the old rusty horrible wheel bolts ruined the nice new look - so I got some new Febi wheel bolts from Autodoc for £30 for 16 of them, which I thought was pretty good. As a comparison BMW charge about £4.50 each and the Febi ones are absolutely identical to the last detail. So much so that I think that Febi must make these for BMW.

Much better!

Did a few other smartening jobs as well that just make it look a bit better all round.

The wing mirrors on these tend to sort of delaminate and "corrode"/bleed around the edges - so for £15 each side, I got new items which look a lot nicer. BMW charge around £50 per side for the mirror glass!

Also, noticed on a previous MOT that it had had an advisory for fuel cap seal. BMW don't sell the fuel cap seal separately to the fuel cap, so it would have been around £35 for a new fuel cap. If you haven't got the my gist yet, you should know I'm not paying that!! :p So I searched the trusty internet and there was someone who was selling the seals on eBay for around £5 for a pair, so I got them and a new fuel cap tether for £3 as well as they always snap on BMW's. Again BMW don't sell the tether separately.

Cheers, it has got a few chips and minor dinks around it, which don't show up in the pictures. I also has as a fairly sizeable dent in the rear quarter which I can't work out how it happened. But it's not too bad at all really. It's not a show pony, and that's one of the reasons I bought this car - I want something I don't have to worry about when it's parked up.

3L 6 cylinder with about that amount of BHP/tonne and a decent bit of torque has always been the sweet spot for (everyday) driving for me personally.

Yeh, coming from a near 500bhp 6.2litre V8 - I thought it was going to feel really quite slow, however I have actually been pleasantly surprised. Don't get me wrong, the C63 goes like **** off a shovel in any gear at any speed and doesn't stop, but the N52 engine in the 130i feels brisk, and even sounds good and overtakes are nice and easy. The whole car, with a proper manual gearbox also, feels engaging, albeit the steering isn't the best - it just has very little feel to it. It's not "bad" as it's still really responsive, but just doesn't have much feel - which is in contrast to the C63 which has really really good steering feel (way better than my M3's). However, when you consider modern day cars which almost all have absolutely dead steering which is slow - it's still a big cut above that.

Don't get me wrong I wouldn't say no to more power, but it is generally about as much power as you'll sensibly use on today's roads/traffic and won't let you down in a pinch, a better compromise on fuel economy and noticeably smoother than 4 cylinders.
 
Need a new fuel cap tether for mine too. Looks like BMW have changed the design of the fuel cap though, I can't figure out how to remove the plastic ring from my cap - there's a white plastic bit on the cap itself that goes around it so I can't see how to get it off without breaking it. Annoying.

 
Awesome thanks.

Did a quick blow over on mine too as they were shabby.

What did you use out of interest?

I've used some spray Hammerite on mine but it takes at least a week or so for it to harden up fully

I used whatever I had to hand which was a can of this in dark grey....


Very old can mind you. Expiry date of 2015 :D
3 light coats and 10 mins DT in between.
 
Nice, I approve having owned a Le Mans blue one for around 3 years, before I decided to scratch the V8 itch I had, so did the opposite of you :p

Mine didn’t have the fancy suspension parts but had a nice performance exhaust, cdv delete and braided brake hoses.

I’m in Cambridgeshire so hit me up if you fancy meeting up sometime ;)

Just as an update - I've done a few extra little things over the passed week or two:

Firstly, the large DISA valve on these is known to go, I wasn't sure if mine had but since it was still the factory original one, I thought it best to change it out as it will have likely been passed it's best. Low and behold, it was broken and I found the flap in the inlet manifold. Luckily it hadn't broken up and been inhaled by the engine, but worrying none the less! Quite an easy job really and again, after working on the C63, I'm still basking in the love of having space in an engine bay. Replaced with a Febi part - I can't believe how much a motorised flap is. The Febi part I got for a good price of £120 from Germany, but the OEM one is around £170 and I think the Genuine part is about £220!

Another thing I noticed whilst doing the oil filter housing gasket was a bolt in the head, seemingly without a head on it. I Googled it and found that this is actually pretty common on the N52 due to the aluminium bolts not being strong enough. As you can see from the picture, access to it wasn't exactly good so I had to remove the bolts for the inlet manifold to get enough space in there. From there, it was a case of getting two picks and trying to rotate the bolt around enough to get it out. Slow work and back breaking due to leaning over constantly. Thankfully, because it didn't have a head and because it's aluminium, it was pretty free moving.

Now, annoyingly, I had to do this job twice, because I actually sheared the replacement bolt also. I said some bad words when that happened. So I had to extract that one, and go back to BMW and get another bolt :rolleyes: I snapped the second bolt due for two reasons - A) you need to reallllly clean out the threads in the head of any oil so you are able to torque it properly and B) I found online the torque spec - but it was the wrong torque. I read that it should be something like 28nm + 90 degrees and then I found the proper TIS and saw that it should be 15nm + 90 degrees. It doesn't matter so much when it comes to steel bolts, but aluminium bolts are totally unforgiving of **** ups.
