Many failures 
Solved
1994 Volkswagen Golf 210000 miles
Good morning, buddies. After being stopped at a traffic light, I start driving again and the car seems to choke a little bit. It is not a huge failure and it recovers quickly, but it worries me anyway. Even more, when the car is stopped, it trembles noticeably and it seems it is about to stall. Even the fuel consumption is higher than it used to be. Injectors have been cleaned and the car tuned.

Check the temperature sensor.

You should check the coil and oxygen and temperature sensors, as these have to do with the fueling system. Some of them must be failing and that is why your vehicle is injecting more fuel than needed.

CommentStarting when cold Solved
1994 Volkswagen Golf 260000 miles
In the morning, it is hard to start the engine and, once it does, the speedometer or cluster blinks. I have read that, in most of the cases, the problem is in the coil, but it can as well be in the fuel pump. Apart from that, the car overheats and starts whenever it wants. It is driving me crazy, I need your help please.

Everything has it logic and you are saying that, when cold, it is hard to start the engine and, when it warms up, everything is alright. Then, it has to be that the temperature sensor is failing or has a bad contact. You can as well try replacing your coil with one that is exactly the same model as your and checking if it is the coil that is causing the problem. Good luck and I hope you can find the solution. If you do, please comment it so that we keep helping others.

Hello, I had a Golf GL 96 and had your same symptoms. They were finally solved when both the TPS sensor and the coil were replaced. The engine stabilized and the fuel consumption was considerably reduced.

Do my car a VW golf 6 TSI with CAVD engine was in an accident impact was on the drivers side we ended up replacing the dashboard and everything, it’s been 2years before I drove it, now it’s back on the road we noticed some errors the most worrying one being the flap regulator, replaced it and car improved performance wise and then came the misfires, and EPC light, checked the plugs they seemed okay nothing to worry about, so swapped the coils and saw the error moving with and then I changed that particular coil and we were good, stepped on it no errors, drives fine but the fuel consumption is… Read complete

I am by no means an expert, but here is a checklist i follow
Coils/Plugs
O2 sensor?
Breaks (partially) locked up?
Air filter'
I have had this issue twice on my older Audi A6 and my Passat. Both times it was the O2 sensor. (I might just be extremely unlucky though)

Thanks mate for the reply, I have checked the O2 sensor cleaned it and the coolant Temp sensor and the Map sensor and so far it seems to have solved the problem, unfortunately I did all those sensors in one go so I wouldn’t really tell which was which but If I was to pick one I would say the coolant Temp sensor, it was corroded heavily than the O2 sensor and the map sensor

It might be the spark plugs or the ignition coils that might be the culprit

I'm having the same issue. I took it to a different mechanic and one of them is saying it is in the low pressure pump and the other one is saying it is the relay. Can someone help me ?
The Jetta Mechanic from Egypt 4 months ago
Change the relay and scan with the computer and check if you are getting fuel and spark because the fuel injectors might be the culprit or the spark plugs or ignition coils

Not solved because we just forged the wiring so that the pump is working but not stopping

The wiring harness for the fuel pump might be the issue

I think it has no spark so the spark plugs might be the issue or the ignition coil

Revving issue
1996 Volkswagen Golf Hatchback,Manual,1.8 120000 miles
My car [1996 Golf MK3] recently started struggling to rev up/accelerate past 2000rpm,with the fuel pump already giving me revving/acceleration issues i have a feeling that i should just replace it?[Its an inline fuel pump]
It bogs at 2000rpm if i can get it to move, and if I'm lucky enough i can get it past 2000rpm if i feather the throttle.

Crank no start
1991 Volkswagen Golf hatchback,manual,1.3 nz ,40kw 160000 miles
Hi, i recently got a golf 2 from 91 with a 1.3l nz engine. A little backstory to this: befor i started to work on it i cranked the car over and gave a little gas via the intake to see if it starts. Well to my luck it started without a problem (i want to make it into a low budget rally car and i found it abandoned with wasps in it and mice). Now, i repaired the fuel system by replacing the fuel pumps with just one from bmw that makes 3bar of pressure. I bypassed the high pressure fuel pump tank so it goes directly to the engine. After that i changed the battery terminals because they were broke… Read complete
