Hi Guys
We are a garage that have sold a customer a Seat Leon 2.0 TDi FR 170 (PD) model. It has had one owner and covered approx.. 45,000 miles with a full Seat service history. Registered in 2008.
Since we sold the car it has come back to us virtually the same week with the following symptoms:-
Slightly lazy to start but not significant. Intermittent poor idle with what sounds like a mild misfire. Whilst this is happening the car emits a unburnt fuel type smell and smokes very very slightly. If you rev it, it clears quite quickly and disappears until it settles again. This doesn’t always happen, sometimes but less frequently now it runs fine. There are no symptoms when driving normally. It has plenty of pull and is very quick. If its been left a while on tick over or maybe for a few days sometimes when you drive off it will smoke much more heavily for a few hundred metres and then drive normally again.
What we’ve done:-
Replaced two injectors that seemed to show implausible values. Replaced injector wiring harness.
Replaced EGR valve which was very blocked. Replaced tandem fuel pump, replaced fuel filter twice
Replaced all glow plugs. Got a releative compression done which showed good compressions on every cylinder both when mis-firing and when not mis-firing. Had injector readings done again. Number 1 and 2 showing implausible readings so replaced this 2. So it’s now had 4 new injectors. It had already had them replaced in 2012 anyway from a product recall. When changing the injectors the head was check for leakage past the injectors. Neither the injectors or where they sit in the head showed any sign of wear whatsoever.
As you can see we have spent a considerable amount of money on this car and its exactly the same. These Siemens injectors alone are a fortune each as you know.
Should we now look at mechanical I.e crack in the head etc?
