Loss of Power

**Dr Spine** · 27-11-2006, 10:34 AM

Hi, on the way home from the recent Qld drive day I noticed a loss of engine power that seemed to last for about 1 second. It was as if the engine had died and then things were OK again. It happened while climbing the Toowoomba range. Other than this and one other identical event a few weeks ago in a different location, the car has been 100%.

Do any of the technically minded have any thoughts as to what might cause this. Have other Golf or GTI owners had similar problems?

The car had only done just over 3000klm from new.

Thanks

If the traction control or ESP came on can cut engine power but this would be if roads slippery or maybe ran over some gravel while accellerating. Otherwise nothing coming to mind for power drop off.

No it couldn't be that. I'm thinking it might be some kind of computer/software glitch???

As I said it's only happened a couple of times.

Am going to talk to VW about it tomorrow.

Sounds like a plan. Their diagnostics should pick up if any faults were logged. Would normally expect the engine light to come on the dash when that happens but if faults gone will go back out. Quality of fuel maybe or water in the fuel tank.
I know with mine until the car is warm i have boost cut kick in stopping me use full power but feature of upping the boost to protect the DSG box until its fully ready.
What part of rev range? When changing gears?

Hopefully something simple and covered by warranty.

I know this may sound stupid but could it be the clutch possibly a faulty clutch?

I have had about 3 lapses in power but not for a full second. Happens at around 4,000 rpm. It has happened under hard accelleration for me. I am yet to plug in vag com but I should get time late next week to check it out. A I say, it has happened with me over a 4 month period. Certainly makes you grab a breath when it happens! If I get time earlier, I will plug mine in and check for codes, will let you know. Cheers!

Thanks for that. I also have experienced a small drop under hard acceleration but it has been a rarity. I've got the car booked in tomorrow to the local VW dealer to "hook it up" and see if there are any obvious fault codes.

I'm no expert but I'm guessing that the problem will be connected somehow with the computer management system.

Hopefully an easy electronic fix will follow. I'll let you know.

VW dealer hooked it up to their computer today and it did come up with a fault code of some sort. The dealer has sent the info to VW HQ in Australia and they are getting back to the dealer as to what to do. At least it should get fixed and not cost me a cent!

not sure if its the same thing, however i've also noticed this same thing today on the regular journey home (entering the sth bound tunnel of the M5 East in Sydney). as I was overtaking another car, there was a distinct flat spot of acceleration in my 2.0fsi jetta. ill be taking it back to the dealer anyway but am obviously curious as to what the hell this is. dont want to overract but this could be a real safety issue if one needed to get out of the way of something alot bigger than the jetta. love to hear from any of you that have experienced the same problem.
