Hi all,

Just a quick one, I have a possible turbo system issue on my 320D E90 again, although different from early 2014 when i bought the car where I had an actuator issue confirmed by code reader, I took it back, as its an electrical actuator I had to get a recon turbo replaced and the bits that are usually done with it. £700+ ish i think

Basically from idle, if you accelerate from 1st there is a flatspot, on the motorway when your between 60 to 80, there is very little power, 80-90 again struggling, it seems to be hitting me MPG aswel.

There is no turbo whining sound that can be heard, no smoke has been seen really. I have checked by unplugging the maf connector plug taking for a drive, plugging back in, I have checked the housing tube thing where the MAF connects to, cleaned around the seals, I am not technically up to scratch where other vital boost pipes are. but I have had a loose around pipes, apart from some oil seem which sometimes happens.

I have had 3 x handheld code readers in, one threw up some old codes that hadn't been reset, taken for a drive and read again, come up with nothing, other readers reporting no codes now.

I cant notice any boost leak noise per say, and actuators usually throw up a code.


Undecided on what im doing at the moment, what makes it difficult is that I am applying for a house mortgage later in the year, so I dont really want to start spending savings on cars or look at finance (I have until Sept/Oct until my current blackhorse finance is fully paid off).

If I need to replace, it will be for a petrol, and I am looking for a cheap fun car, but dont know what, maybe something like a Masda - MX5 but have no knowledge of them, they seem a good punt? is it the turbo model 1.8T to go for? 144 something BHP? or any others that I could pick up for maybe £2-£2.5k? which hopefully will have no major issues on purchase.


If the repair costs on the 320D are not that of replacing turbo etc then I may concider a PX.

How many miles as it done? These kind of issues are pretty common on high mileage diesels, happened to my Audi (turbo went bang, oil leaks, low power, etc) :/

It's usually a symptom of something else, probably a result of years of crap building up in the engine. You find that replacing parts just holds off the inevitable and it eventually goes wrong again. I've stuck with petrol ever since.

MX-5 is a good bet, but check for rust.

96K, bought it on 60K when I had to have it returned to the workshop to have a recon turbo under warranty (Just caught it) because of the Actuator.

Yeh heard to watch out for Rust on MX-5 - Is this in any specific place?
 
I think it's the sills that go on the older ones. You might see some bolts rusted in place on the underside, but that seems to be normal for Japanese cars :p
 
I had my turbo replaced on my e90 with a brand new one, it ended up costing ~£1200, 4 hours labor and the new turbo within that price.
 
Outch. I would probably go for another recon if it came to that. I am not sure if I'm going to be keeping it for another 2 years. Maybe 1 if i did.

Tonight cleaned the mad sensor and had a quick check on the front turbine which appears to spin ok.

I don't really know much about getting to/checking turbos.

I may have to pick a garage and see if i can more manual checks done. Mention to them its now been through multiple code readers with nothing showing
