Just had my car fail its mot :(

Just wondering what the next steps are for the failure.

no1

Emissions are to high, i havent got the fail sheet to hand. But im thinking of buying that "stuff" you put in your tank and supposed to help with emissions....

no2

Front brakes are not balanced. Offside is pulling a bit. I have never noticed this, but hey it failed on it. I am going to strip out that side and see if i can see any obvious problems. Im thinking of doing new disc's and pads?

So would new pads, discs and that "stuff" be a good start?

I gave it a blast before mot as well, to get it nice and hot.

If it matters, car is 1.8T GOLF MK4

Thanks
 
Just strip grease and reassemble existing front brakes (caliper slides etc) that'll cure the brake imbalance (assuming you don't have a caliper on the way out)
As for the emissions, is your engine management light on? if not yeah stick a bottle of that stuff through the fuel, usually works ok. If it doesn't then I suggest getting a diagnostic check done to see if there are any sensor gremlins lurking that havn't yet triggered the light on.

The car has gone from being used daily, to being used maybe once or twice a week. So sticking caliper is a good hit. Didn't think of that DOH.!!!

Nah no emissions light on, would vacuum effect emissions? As i found a slight split in a small vacuum hose. But it was too late to fix it before mot. So bodged it with tape. But covering the hole, doesnt make the car idle any better or worse
 
A split vacuum hose could certainly affect things and as the 1.8T vacuum hoses seem to be made from cheese, I'd recommend having a good hunt around for any others that may be damaged as you'll probably find more than one.

I'd also suggest removing and cleaning the throttle body with some carb cleaner as it's probably caked in crap. Bear in mind though that it may need resetting using VAG-COM if you play around with it too much while cleaning.
 
i would not bother putting anything in your petrol. the car more likely needs a full service, maybe a lambda or a cat, or like you said the hoses need replacing for a leak, sucking in extra air wont help it at all. the emissions sheet/mot tester should tell you what the problem is.
 
I'd be reluctant to fit another until you find the reason that one has died..
Or your well spent wonga wont last long.

Or do what most people do, keep a cat for MOT time only and run it decat for the rest of the year.

Prob age has killed it. Its 11 years old the cat.

Plus i have been running 250-350bhp through it via a side exit exhaust. So no doubt this has killed it. But its just strange for it to fail one year by loads. But it down to the cat.

And yes once the mot is done, its coming off and running no cat what so ever :D
 
I would ask friends and family if they know a friendly tester? One that will possibly forget what car his moting and will put it in one with a cat! It sounds like your golf has a decat? We need more pics and specs of this 350bhp?

Well it must have cat, the exhaust is one big bodge. I admit that.

Spec wise

its basically had this fitted, all bar a few parts

but i didn't use my 150 block, i went for an audi block 225 bam code.
I will take some pics, when i get it back from mot :( Its not been on the road 5 minutes :(
 
When you say the exhaust is a bodge what do you mean? Litterly hanging off or just because it hasnt passed it's mot test? It sounds like it will be good fun at 350bhp! Bet it's a bit keen on the front tyres!

No no no lol, its just loads of small pieces of ally pipe all welded together to make the exhaust up, out the side if you get me. Ie side exit exhaust.

Maccy has seen her. its a chav car, coz of the exhaust and rear lights.

Let me see if i have a video
 
will sort the video out, its when it was running decent power :D

side exit :D

Yeah its fun tbh, but it needs all sorting out now. Prob running around 250bhp. As i/c is suffering from heat soak badly!

But i have sold me bbs ch's and using the money to get her sorted. Its going back to standard looking. So its a bit more of a surprise. But with 16's on it fun ;)
 
Ah I see does it even have a cat then if it's side exit? I would look on the owners club or ebay for a second exhaust exhaust but not standard if your running that much boost and power! also just a thought if you are running that much more power and they are testing the car on standard given emmissions it will be higher. I would find a friendly MOT tester!
