[Solved] ESP and Engine Malfunction Indicator Light Up in VW Golf 4 2004 130 KM, 1.9 TDI, Estate, Quatro

VW Golf 4 2004 130 KM, 1.9 TDI, estate, quatro

At the same time, the engine malfunction indicator (AB gas which translates to the flue gas workshop) and ESP lights up. I have no idea how it is connected but it also lights up simultaneously. You can feel the symptom - the engine has a light mule and then after about a minute of driving turn on. And if there is no mule, it's all ok. If they turn on, they will go out after a while. When the controls turn on, the computer does not cut power or turbo. Just the car goes with this light mule and after a while passes him. I have recently changed the timing the rest unchanged. Does anyone know what's going on? Maybe the fuel is of poor quality? Now only b7 ii so it is not known whether it falls within the norm.

I had Bora from 2002, 1.9TDI 101KM, 4motion.

For example, the failure of the rear wheel speed sensor caused the lighting of up to three warning lamps: engine faults (check engine), faults in the traction control system (such a sliding toy car with a triangle) and ABS faults.
This is due to the fact that these cars in the all-wheel drive version have a very extensive traction control system, with the possibility of limiting the engine power, inclusive.

Unfortunately, there is no suggestion of displayed messages. It should be (in my opinion) connect to the OBD connector with the VAG interface (or other good tool), delete all existing errors, wait for the appearance (re) of this fault and check what NEW errors have appeared. Only with such information you will be able to try something to advise.

I know (not from my experience, but still) that the 4motion car, in which the tires on the front and rear axle differed significantly in wear, had periodically the symptoms of 'power weakness' which completely subsided after the tire change on identical on all four wheels. The operating instructions recommend that you maintain identical pressure in the front and rear wheels (!).

This does not result from the 4X4 drive only due to the fact that all cars equipped with ASR or ESP for the operation of this system use the regulation / reduction of engine power, this is why the damage in the ESP / ASR system is also signaled by the engine control failure.

Perhaps I expressed myself imprecisely.
My point was that the cars of this brand and this year, in versions equipped with the drive of all wheels, have the ESP system more 'restrictive'.
Or maybe I should write that the 'classic' versions - if they even have ESP, it interferes with the work of the engine in a significantly milder way.

These are my own conclusions from the comparison of driving such cars and I would not like to unleash here the proverbial 'storm in a glass of water'. If someone does not agree with me, it's hard. Today I have no way to prove anything about it.

I am convinced, however, that the holder of Golf IV version 4motion must be prepared for the fact that it may have problems originating in the ESP system, and caused by 'trinkets', which in normal versions do not cause any negative effects. That is why I joined this remark about the tires in the previous post.

Conversely, the engine fault lights the esp control. The ESP must have an efficient engine to operate.

The size of the tires must be the same, that's all.

After the change of the petrol station, the symptoms subsided. It turns out that once I filled up an empty tank with a bad fuel. I left them with these errors and refueled elsewhere and everything went away.
