Golf V GT 1.4 TSI 125kW Misfire

Good morning!

You are my last hope!

Yesterday, I went to look at a Volkswagen Golf for a friend.
Let's run a quick scan first, everything seems clean.
Then I let it idle, the dealer didn't have any red "Do Not Operate" signs available, and I took a look at everything else.

When the engine was idling and had warmed up somewhat, I noticed a very slight hesitation and occasional misfires.

MWB 15-17 read, and while it was running, it barely registered any counts despite the fluctuations. However, when the speed was increased to 1500 rpm, a total of almost 300 misses were counted before it automatically reset (within 1 minute?), with nearly 200 of those occurring on the first cycle. Cylinders. 0 failures for any of them.

Regarding the car itself: It's a 2006 Golf GT with 149,000 km on the odometer. It was originally owned by the same person until two years ago, at which point it had approximately 130,000 km. However, the problem seems to have existed even with the first owner: At 123,000 km, VW performed a pressure test on all four cylinders, after which four new fuel injectors were installed. Immediately afterwards, four spark plugs and ignition coils were also replaced. At 144,000 km, the timing chain was completely replaced, including... Sender, swapped.

Problem: The dealer is only selling the car on behalf of a customer. The previous owner says, "This is NORMAL for this engine; it's always been like this, and I never had any problems driving it." Then I wonder why the error memory seems to be cleared again beforehand...

The car is beautiful, in excellent condition, fully equipped, has a new technical inspection (TÜV), and the price is reasonable.
But these glitches are giving me a stomachache. Unless you have the patented solution.

Thank you for reading!

Greetings.

Hello.

Without having seen the golf cart, I'm guessing it has a broken piston.

Hi Sascha,

...if a seller is already putting a car on consignment, I would be a bit cautious. My nephew once almost got scammed during a sale. He was only able to get out of it thanks to a good legal insurance policy. So, I think the dealer knows more than he's letting on, and the seller is hiding behind the excuse "it's always been like that."

But maybe someone here has other ideas and suggestions...

Greetings, Styrian.

Please send me the vehicle identification number (VIN) via private message. Then I can check what work has already been done on this vehicle (but this only refers to work performed by the dealer).

Hi Sascha,

Has Dombay gotten back to us at all?

She hasn't contacted me again.
There are some strange people out there. First, ask for help, and then don't respond anymore.

Hi Sascha,
