3litre diesel smoking badly

Hi everyone after suffering a badly smoking 3litre diesel and spending approx. £2ooo pounds last year to get it fixed with no satisfactory result I decided to bite the bullet and book it into a Fiat main dealer garage, expecting a humongous bill, I was very pleasantly surprised to be told it was fixed at a cost of £58.00.
Just goes to show that (back street garages) are not always the cheapest.

The reason for it smoking was because the engines software had not been updated since 2010 and because of that it was pumping too much fuel, the problem was found when it was plugged into a Fiat diagnostic machine which the other garages did not have.
It took about an hour to do all the downloads.

Jan, it's unlikely he will have the official Fiat unit, most likely the generic unit most independents will have, which I'd guess was the unit his previous expense was caused by.
The generic units do not have full access to all features of the operating ECU software and very unlikely to have the ability to alter and or update the base information within the vans computers.

Worth asking him though, he may have spent the many thousands of euros it would cost.

Modern engine ECUís are highly complex computers these days, they monitor a huge variety of parameters and then the algorithms work out exactly whatís needed. You need a highly specialist diagnostic system to check itís all doing EXACTLY what it should. As has been demonstrated it often works out LESS expensive.

I would liken letting anyone other than a main dealers diagnostic kit loose on my car the same as asking a Chiropodist to perform complex brain surgery on me. Basically it ainít going to happen. Having said that they might improve matters inside my head!

Oh yes, I don't remember how many thousands it cost but it was several a few.

P.S. Hans says he thinks Gordon told him it was around 3,000.00Ä

But itís totally useless if he doesnít know how to interpret what his computer tells him. Generic software is unlikely to be as complete/up to date/accurate as that which is provided on a regular basis by manufacturers to main dealers.

My car went in the other day for a (Free) software update to smooth out the drive train (itís an automatic) what used to be a pretty smooth gearchange is now imperceptible (unless using silly amounts of throttle of course) The only clue is to watch the tev counter drop! Amazing technology.
