BMW turbo charger

FMR1

Hi,

I have a 2002 320d BMW, 17 months ago I had the turbo charger replaced. Now it looks like it's gone again:(. I service it on time, haven't had any major issues otherwise. Is it normal for the turbo to be gone again? Any advice would be appreciated.

Thanks.

Try the normal motors forum, this one's about doing DIY work, you're more likely to get a better answer there.

Did you or has the pcv filter been replaced lately. Its up on the rocker under a hosuing with 3 scews. the filter looks like a litte cotton reel.

you say its been serviced on time? can you confirm that the breather filter has been replaced during those services?

not an expert but i believe there is a problem with a butterfly valve that breaks and gets sucked into the turbo and destroys it

as a matter of interest how much did the turbo job cost you

Are modern BMWs not reliable? I read M5s need the vanos system replaced at a cost of 8 or 9 grand at around 50k miles. Add to that all the electronics and sensors and Id run a mile personally. I might consider one later on but an earlier more reliable model;)

I have been using the same mechanic for years & he is really good to me so I am slow to start questioning him as if it's his fault. I don't know about the pvc/breather filter. He did mention some filter that is supposed to be changed every second service & that has been done. He knows the car & knows that the turbo was done. Should I be asking those questions?

The turbo cost €1100 all in, last time.

Thanks guys.

Thanks for moving the post too.

that sounds like he did change but double check that he did change the breather filter to rule it out.

also the swirl flaps are a common problem on the 20d BMW enggine, they break off and get sucked into the engine/turbo and due all sorts of damge!. ost people remove them, theres a good few write ups about it.

This is a question more than a statement, but I keep hearing people with big problems with BMW diesels both here and in the "real world". Considering how few of them were sold compared to 1.9TDIs and HDis, would I be right in saying they are not the most durable?

good question, but 90% of the problems are down to the owners not changing the breather filter every second or so service and not checking the swirl flaps often enough, or also the mechanics that service them not knowing what to check on particular cars.

Most diesels aren't. The Irish public is about to learn this in a few years with the majority of cars being sold being diesel , many think they are saving the planet and road tax however any savings are quickly lost with high maintainance bills and low co2 is a joke. It doesn't make one jot of difference. Old diesels were reliable, but modern fuel injection operate at very high pressures along with turbo issues where a turbo is needed due to the sluggish nature naturally of diesel. Also the engines are heavy which means that the wear on the suspension is greater along with higher weights which damage handling. The engines are unwilling to rev and feel sluggish even if they aren't..

If i recall correctly BMW 320's before the facelift in 2002 have little turbo issues but any 320d from 2002 onwards are notorious for turbo failure.

a turbo all in for 1100 sounds like it wasnt a new turbo unless he did the job for free , probably second hand or reconditioned , and they never last , if done right should last a lifetime ,as said the breather filter is very important , he should have done an oil change aswell , the swirl flap would wreck the engine not the turbo , although it is a common failure , so if you havent already done so blank the swirl flaps , i have had 9 bmws i know them very very well and replaced the turbo on my old 330d and my girlfriends 320d , they should not fail if he did the job right and used a new turbo , unless you really drive the crap out of the car and never give it any cool down time after that

Thanks everyone.

I'm pretty sure it was a new turbo, it had a 12 month warranty. I'll double check. I will also ask about blanking the swirl flaps & the breather filter (I will have to write this down, I feel like I'm learning a new language. My mechanic is gonna laugh!).

I don't think I drive the crap out of it.

I keep hearing that BMWs have turbo issues but I didn't hink it was going to be every 17 months! Is that what notorious means?

Confirmation of diagnosis due tomorrow..

That is a completely different problem, the "butterfly valves" as you call them are actually swirl flaps located in the exhaust manifold and can enter the engine, not the turbo. This is a problem on a few makes, including ford, so its not BMW specific.

If owners (and service personnel) followed the recommended intervals for changing the breather filter, and removed questionable swirl flaps, there would be no major problems. Its like every car though, if they are maintained correctly, they should not give any bother.

That would be 150bhp models up to Nov 2003 when the turbo was upgraded to a newer version.

Generally, late 2003+ models are reliable, with 2002/2003 models being prone to turbo failure. Again, lack of changing the breather valve can cause problems also.

you keep hearing that from the owners that didnt look after them tbh.
theres no issues at all once you know what tochange and when to change it.

as a matter of interest how do they enter the engine, are they not blown away from the engine in the exhaust manifold

The flaps control the recirculation of exhaust gas back in to the combustion chamber to reduce emissions, so if the spindle holding the flaps break, the flap has nowhere to go but into the cylinder.
