Help!....PSM and ABS warning light
- Thread starter ggrantw
- Start date
Ok .. Brakes all locked on and i think its the master cyl .. the C4 i worked on a few years back turned out to be a bent retaining pin in the master cyl .. the customer liked to drive it agressively and often had the PSM kick in .. some how this caused a back pressure in the master cyl and led to this happening .
We cracked the brake pipes at the master cyl to reduce the pressure and enable the car to be moved ... you could crack off each brake caliper in turn to reduce pressure as well .
For you this is a garage job as im guessing here and the above fault is something ive only seen once BUT it was a C4 so thats all ive got im afraid .
