Hi guys,

I was wondering if anybody can help shed some light on what could have caused this please.

I was driving the car uphill, full throttle and then the engine just cut out and refused to start. I've checked a few things and eventually got it to start without the turbo pipe that's connected to the EGR in place but it cuts out when I try and pull the clutch up, even with my foot to floor. I'm not sure if that points towards an issue with the intercooler, turbo or maybe something else?

Any help would be greatly appreciated, thanks in advance

Could be a stuck EGR valve fully open but reckon best to get it scanned to hopefully pinpoint something. You could look for days and not find out whats causing it.

As the engine was under maximum load , could the turbo have seized ? Can you access the impellor and see if it spins ?

Thanks for replying, I have had a mechanic out to scan it for codes but it doesn't have any.

Thanks for replying. I'm not sure, I didn't hear any bangs or have any black smoke out of the exhaust which you usually get from blown turbo. Could the turbo just seize up quietly and then cut the engine out like that?

Might be the anti-shudder valve stuck in closed position. May be able to see, or get phone camera to look, with right angle hose removed.

Thanks Pete but no, it's definitely open. That right angled hose is the one I removed to get it started, once that hose was back in place, it refused to restart

Reckon as said you should scan it for codes. Got to be something thats caused it.

Yes as I said earlier, I have scanned it a few times, but there wasn't any codes at all. I agree there should have been a code but no.

Check the other main hoses as well. Had one blow off the intercooler on mine. Car started but wouldnt rev at all. My own fault as I hadnt clipped it back on again properly but it lasted a month before coming free.

Thanks, yes I'll check those but I'd be surprised if that's the culprit for me. I would have thought if that was the case for me, it would at least be able to start as it did for yourself.

While your at it check the intercooler isnt full of oil or clogged.

Will do, thank you! I'll keep you all posted

How does the EGR look inside? They love to get sooted up

It looks okay, there's a bit of carbon build up on the flap inside but only minimal.

I've just realised I'm talking about the ASV and not the EGR, I will endeavor to check the egr valve as soon as I can get to the car! I'll keep everyone posted. Thanks

Just a quick update: I've had a look inside the Egr passed the asv and it doesn't look too bad for carbon.

I can't reach the intercooler to check it but the hose that comes out of the top is coated in oil, but it has been that way for some time to be honest. I don't know if that points it more towards the turbo leaking oil over time.

Still no codes on the dash either, which is strange

I find theres always a bit of oil in the pipes but if its high up it may be that theres a fair amount in intercooler.

Yes I guess that makes sense.

I'm still in the process of diagnosing this and I've got it booked into a local garage that can hopefully diagnose it but I was just wondering if you guys can help me with understanding the exhaust gas route from the engine please.

How does it get from the exhaust manifold to the back box?

The reason I ask is I'm struggling to understand why the engine freely fires up without the 90 degree pipe leading to the ASV but can't start otherwise.

As far as I know exhaust goes from manifold to turbo then cat and into exhaust system/box. On my BXE theres an egr cooler that takes some to egr valve. The PCV valve is on the air intake side. Just wondering if it starts with the air intake pipe off the PCV it might be lack of air or perhaps a blocked/failed cat. Check that your airfilter is ok and hasnt clogged or collapsed.

Alasdair

Thanks for the explanation, that sounds quite similar to what I thought as well. I also believe that it is most likely an air intake issue. As for the air filter, I'd removed the hose just passed the maf sensor to try and it didn't start then either, so I'd say the air filter is okay. I will check the pcv valve before I put all the blame on a failed turbo. But I would say it's not looking good at this point.

Thanks very much for the help so far,

Tom

Hope its something simple thats been missed.

Alasdair

Not sure how easy it will be to access but if you can remove turbo inlet pipe and see if the turbo is actually turning. It should spin freely by using fingers.

If its seized or blocked somehow it might explain the car starts and idles but dies on revs.

Alasdair.

I'm just wondering now, does any

I've been to look at it today and I've taken the hose by the air filter and Maf sensor off in better lighting and there's a lot of oil in there along with shards of metal. Also when running, there's a suction on the inlet by the Egr and Asv valve but there's a blow on the inlet by the PSV valve which I would say is exhaust rising up through the intake along with the oil. I'm assuming that this is definitely turbo failure at this point?

Many thanks,

Tom

Shards of metal are never good. Think the only place they could come from is turbo. If it is then you will have to clean everything up including intercooler before replacing. Then I would do an oil/filter change and then another at say 150/200 miles in case theres anything that could damage new turbo left in system. Normally when turbo goes theres loads of smoke unless its the turbo veins that have disentegrated and seals are still fairly intact. Had a quick look online and the turbo seems to be around £200 new which is fairly reasonable. Neighbour have a people carrier and their turbo was just under £1000 plus fitting and that was at a very reasonable garage.

Alasdair

Thank you to all of you for your help! As always, very much appreciated.

Kind regards,

Tom
