Hi All<p>Just need some advice and help:<br>I drive a 2006 S60 T5 GT<p>Issue:<br>Since December I have been experiencing this problem with the car sitting at the dealer trying to diagnose for almost 2 months intermittently.<br>It starts with the chech engine light. Volvo checks and following protocol go through logical steps based on the error codes. Fuel tank flushed, fuel pump replaced and fuel control module also replaced. Car runs fine for a month and then I get a check engine light again (but car is still driving normally). <br>Take it back to my dealer, and they check the engine codes: fuel pressure. The monitor the pressure and see slight fluctuations which they say is not normal, so I book the car in for fixing. They pretty much go through the same process again, but after taking a fuel sample, the fuel is almost murky black with sediment. Volvo claims it prolly the fuel then, and after doing the necessary pump replacement and tank flushing, release the car to me as sorted. Day one they car goes like a bomb. Day 2 I start experiencing slight hesitations on acceleration and eventually the car dies altogether while driving. If the car is left for a few seconds, its starts fine but dies again after a few kilometers. Happened 4 time in a day and I subsequently send it back to the dealer. Check engine light also on again.<p>THe car is now back with Volvo doeing the entire process again, tank cleanup etc. The new fuel sample even after flushing and using fuel from their own filling station (can't blame my filling station on fuel quality) is black agaion. They are still awaiting the tank to return before putting it all together and testing.<p><br>Anyone else experience anything similar? I dont believe that the actual fuel is causing the problem but rather a faulty fuel pump or the electronics.<p>Advise appreciated..
