i'm drunk, in charge of a keyboard. well not that drunk, but drunk enough to boreyou to death.
I bought a the timing crystal (the bit under the drivers wiper blade on a mk2 that does the pulses to the distributor??!) to replace a crystal which was going faulty. apparently a full kryton tune (or whatever its called) can show you the unit breaking down, and in time its worth replacing.
So, i replaced it with a Lucas part from GS, they were werent F at the point.
Unfortunately, i broke the original VW part getting it off after getting the new unit. No matters, shoved new Lucas part on.
Instantly car developed a mis timing over 5.5k rpm. 5.5k became 5k in one day and within 3 days was down to 4k.
Took the part back to GS, and they swore blind it was okay.
Took the car to my mechanic, told him the story. He had the car for a week and checked (apparently) every electrical component to find the problem.
After 4 days, a mate brought an 8v to his garage anfd they swapped timing units to see if that cured the problem. Lo and behold - my car was fixed.
Lucas/GS part = 40 quid
VW part = 120 quid
My garage screwing arounf = 270 quid
1) i never used GS again
2) i never used that garage again, despite being a loyal customer for 4 years again either.
3) buy the part over the VAG counter.
Life is cheaper and simpler in the long run. And when the VAG counter get it wrong - you can shout at them.
