This is always a problem.
The main question i get is can you quote before you do the job.
Well basically no. Diagnosis take’s time and time needs to be charged as we sell time.
When a fault code brings your engine light on it’s the starting point for us.
If we carry out fault tracing and repairs sometime’s the light come’s on again for a different fault but the same light is used, making customer relations very hard, but we do fault trace wiring and sensor fault’s and this is not easy but it’s why allot of people use us, faulty or wrongly setup wiring just causes issue’s, So when you get a cheap estimate for wiring your new ECU in it’s going to cost you more in the long run.
We’ve run out of stock so back to the long process of fault tracing & repair, restocking date is unknown
