Hi All,

My other halfs FR ('07 Plate) seemed to lose all boost over the weekend, was fine to drive but just like there was no turbo at all.

Took it to a garage expecting it to be a blown off pipe as I'd had the radiator replaced only 2 weeks ago.

They informed me it was the diverter valve and that they'd have it fixed by the afternoon.

Well I just picked it up and they told be that on boost it was fine but low down it seemed to be low on power (low down felt fine before) and also said that there was a timing fault code on the car but it was ok to drive away.

I got all of 200m away, up to about 3,000rpm (the car was already warm from their test drive) and it just spluttered and instantly cut out (the rev needle just drop like there was no resistance). There was no mechanical noise either. Power low down felt much weaker than this morning when I drove it in.

I put the clutch in and rolled in to a stop next to the kerb and attempted to re-start it (spinning over but sounded like it was never going to start up). So I went back and explained what had happened, they then came over the road and plugged in their diagnostics machine but couldn't find anything?

They've now pushed it back into the garage and given me a courtesy car but what could this be? I feel like it's going to be expensive...

Sounds like hpfp (high pressure fuel pump) failure. Search for it. Loads of info on it, and not cheap to repair once it's too late.

Well it turns out the timing is out and it's now damaged intake valves with an estimated repair bill of £1500 - £2000???

I'm really struggling to understand how this is possible?

When I drove it in to the garage, it drove absolutely fine, just minus any help from the turbo. Low down it pulled fine, as it always had.

They are trying to tell me that the timing chain was out to start with and would have been what kicked off all the problems?

Am I being led up the garden path here?

The timing might have been off since you noticed power loss on your car.

But they should have checked that when you left that car there and they shouldn't have let you drive off like that.

In my mind its their fault for not fixing it until it was too late.

I wouldn't say you're being led up the garden path, it sounds like that genuinely is the fault. But they told you it had a timing fault and it was OK to drive away. To me that is their mistake for not realising the timing was out. My question would be how it has ended up out. The timing chain only drives the inlet cam from the exhaust cam I believe, and that's inside the head so why would they have any need to mess with that?

This is what I mean, I simply don't understand how it drove fine, sounded fine (minus turbo) before I drove it in, they changed the DV and then this happens. It felt noticeably different driving away from the garage (for the whole 200m or so) than it did driving it there in the morning.

I'm really not sure what to do now.

i'll be honest, any car that comes up with a timing fault should NOT be drove without having the timing inspected to make sure it hasnt gone out of the correct timing, Garage at fault in my eyes as you took it in for Diagnosis and they failed to diagnose it correctly and as said they told you it is fine to drive away WITH a timing fault code. Poor garage if you ask me

Well a bit of an update, the car is still with the garage.

Following a conversation I've just had with the head mechanic, it's not the timing chain or tensioner but instead the sprocket has come away from the camshaft and the camshaft is cracked.

What I don't know is whether that happened as a result of the timing going and the pistons hitting the valves or whether that went first which then caused pistons to hit valves.

I did get a print out of the fault codes they read initially:

P2261 - Exhaust supercharge air circulationvalve - Mechanical fault
P1602 - Power supply - Too low
P0011 - Camshaft timing retard(Bank 1) - Target value not attained
P0016 - Camshaft timing advance(Bank 1) - Incorrect assignment

Now he said that they cleared the fault codes prior to doing any work and the only one to return was the first and so no investigation into the others were made.

I've looked up these codes and it seems as though some sort of physical inspection probably should have been done?

The mechanic is adamant that they are not liable but my point is that low down power was absolutely fine when it went in, it idled fine, sounded like it always did just no turbo. They identified a possible timing issue amongst the fault codes above. They changed the DV and on the test drive found it to not make the power it should low down but on turbo it was fine. The suggestion was that I put it on a dyno to see why but other than that I was ok to take the car away. 200 meters later, valves hit pistons... (so I couldn't verify that on turbo it was fine...).


Ughhhhhhh

Those fault codes do seem to suggest a timing issue was there prior to them looking at it. The camshaft timing faults could've been due to a stretched chain that links the two camshafts or the chain tensioner itself?

I've never seen a camshaft sprocket come away from a camshaft either, bare in mind I've only been working on cars for just over 9 years

As you said it does sound like that damage was caused after you picked it up, but there won't be much in the way of proving it either way.

Although with the fault codes they have kinda shot themselves in the foot as the timing should've been checked prior to further diag work.

Absolutely gutted Marshall, a guy responded to that thread selling a BWA head that had been freshly skimmed for £400.

I'm now on the look out for a replacement head I think, anyone got one kicking about?

Thanks,

Joe

Another Update!

Well, it turns out, no valves hit the pistons...


There is nothing wrong with the timing chain or adjuster.

The sprocket on the camshaft has cracked causing it to rotate on the shaft itself and as such put the timing out.

Total bill, £1714.67.

So, the revised question is, does anyone have a K03 Intake Camshaft?

IMO they should never have sent the car back out after it threw a timing code if they didn't investigate what caused the code.

I agree that they shouldn't have but it actually hasn't caused any damage to be fair to them, I think they got lucky.

Essentially, if they had looked into the problem when faults occured, the fix would have been the same.


The breakdown I have is as follows:

£617.56+VAT to repair the head (includes cost of a new camshaft, pressure tested, valves lapped back in, head skimmed, head gasket kit (apparently £180?), £150 of labour for the head work (done by a specialist))

£12 hours of labour at £49.50 + VAT per hour (a reduced rate from £55+VAT)

Oil, Anti Freeze, filter, cam belt, water pump £217.33 + VAT



Christmas is cancelled :(

As the car threw up the timing error they should never have let it move until it was sorted,basically it wasn't fit for purpose it may be worth ringing trading standards.Personaly I think the bill should be with them not you.Fair play for keeping it cool I'd be banging heads together in this situation.Was it a seat garage ring seat UK if so.
