Hi all,

I asked for some help in the Multipla section, but also wondered whether the 1.9 JTD engine is also in other Fiats so maybe I could get some more advice?

Anyway, it's a friends Multipla 03 1.9 JTD. Was running ok, but then it started mis-firing and kangaroo'ing at low speeds. The induction noise was considerably louder as well.

It seems to have lost power and won't rev over 3000 rpm in any gear. If you try and rev it, it feels like a rev limiter is kicking in.

On top of that, the power steering pump light has come on, and now when you switch the ignition on the dash gives the warning "Engine control faulty - see garage".

Is this bad or is there anything I can do to it myself? I've driven it before in the past and it really flew, but now it seems like the turbo isn't doing anything.

Any pointers of what I can do and where to look? Also, any descriptions/ pictures of what I should be looking at as I've never done any work on one of these engines before. Or is it a case of taking to a dealer for diagnostics?

Many thanks for your help,

Chas

I'm still learning about the JTD engine as i've had my stilo for 3 months, but I would have thought it would be a diagnostics job really if you have the engine fault light on.

you should be able to hear the turbo at about 1700-1800rpm.

:yeahthat: Sounds like a sensor problem. Diagnostic test would be the best solution

turbo could have chuffed it! lifespan on turbos really should be more like 80-150k for a low boost'd car, and less for a high boost application, HOWEVER there is some fate with these things, IE a brand new expensive job with whatever internals that is just a few 0.1g's out of balance will last about 10k miles, wheras one with cheapo stuff and well balanced will more or less spin on forever

Just the luck of the draw!!

take it to a garage (and for hells sake not a fiat one unless its the last option) and see what they think. modern cars are all about electronics and sensors and TBH it really gets on my tits as you can't really diagnose much with them

Cheers for the suggestions guys

There was also a similar thread in the Multipla section that I answered in more detail:

Took the ugly bug Multipla to the Fiat dealer (sorry Faster4_tec, but it's only just up the road and meant I only needed a 10 minute walk back after dropping the car off!) and surprisingly the guy I spoke to was VERY helpful and got the car seen to within half an hour

Turns out that a turbo overboost pipe has come adrift causing the problems. I reckon it got dislodged on the pot hole ridden roads of London With the diagnostic test and the refitting/ replacing of the pipe they reckon it will cost about £90. If that's all it costs I'll be quite impressed with the speedy service and low costs (they could easily charge for replacing ECU's or something). Even more surprising is that the garage didn't have a good reputation, so I'll be pleased to find they have indeed improved and will post up comments on here.

Anyway, they're keeping it in until Monday because it's also been seen to for a suspension spring recall. I'll report back as to how it all went.

Cheers!
