I call my call Inspector Gadget because it shifts on it's own. I could be braking and it leaps forward as if I put it in 4th or 5th gear. I heard of gears "slipping" but it is the reverse - it's rev's on it's own and speed increases. I was told it might be the manifold but I can't get that confirmed from auto mechanic and it won't pass smog now.

The Golf is the tdi diesel version. Is equipped with a dsg style auto transmission. The shifting between gears became very rough and and vehicle speed surged up and down while in gear. Clunking noises from engine/tranny compartment. Speed hard to maintain. Has been in VW dealer shop twice now for attempted repairs. First repairs entailed replacement of "mechatronic" unit. Was reasonably successful for about 500 miles and then failed in same fashion again.

I have a 2010 VW Golf tdi. I was driving along at 25 mph when my glow plug & check engine lights started flashing, and my tachometer dropped to zero, indicating a stall. The power steering also started to cut out, but I was able to safely pull over. Tried starting the car again and got nothing. The car was towed to a VW dealership down the street, and on Monday 11/19 they informed me that my high-pressure fuel pump failed and sent metal fragments through the entire fuel system. The car is currently being repaired under warranty, but I was told that the bill would be at least $5,000 for this kind of fix. Oh yeah, this also completely ruined my travel plans for thanksgiving, as VW refused to give me a loaner car while this documented warranty issue was being dealt with. After doing some research, I found that there are several cases of 2009-10 tdi fuel pump failures with the same symptoms. Apparently, there have been three revisions of this pump since then, and I am due to get the newest one. But, there is also talk that ultra-low-sulfur diesel fuel in the us is not providing the proper lubricity, and thus causing the pumps to fail (this is not an issue in europe). Nonetheless, further investigation by the NHTSA should result in VW doing a proper recall and redesign, rather than quietly fixing an inherent flaw on a case-by-case basis. Even with my car fixed, I'll still be wondering when this will happen again. Which also makes me wonder if I should just sell it and be done with VW. Very frustrating.

Upon making a lane change to merge into a faster moving traffic lane, the vehicle accelerated normally for one second then lost all engine power leaving me in a dangerous position. Upon depressing the clutch, the engine stalled. I was able to restart the engine after which it worked normally. This has happened approximately 20 times since. It usually creates a dangerous situation such as leaving the car without power in an oncoming traffic lane during a left turn or moving too slowly in a merging maneuver. Sometimes the check engine light will also come on and the glow plug warning light starts flashing. Clouds of white smoke always appear at the tail pipe during the power loss. The dealer has replaced a sensor 4 times which makes the warning lights go out, but the engine cutting out problem is never addressed. VW simply state "cannot reproduce problem" and return the vehicle. The behavior is very dangerous.
