Could this be a cam position sensor fault. Are they reliable?

I would be more focussed on the suspension first. Changing steering geo under different loads indicates something moving in the suspension or steering gear, probably something loose. Go over all the bits you worked on and then the rest of the suspension. And don't drive it till you find whats wrong!

Scan with VCDS might also help. I had random locking/unlocking on my Fab due to a failing door lock microswitch. Worse if on bumpy road so I thought it was due to the car body flexing relative to the door and jiggling the lock. VCDS showed a fault with the front passenger lock and a new lock cured it.

After two problem free years on the 1.4 16v BBZ engined Fab it has started to run rough and showed a CEL. VCDS reported a misfire on 3 which a new coil on plug cleared. Unfortunately I noticed that the air pipe on the EGR valve had fatigued off or been broken of the body so I fitted a new EGR valve, cleaned EGR pipework and throttle body. TBA went fine with the full VCDS I have but EGR adaptation gave an 'ERROR'. I have repeated the EGR adp a dozen times. Each gives 'ADP Run' in the box on switching from memory blocks to basic settings for about 2 seconds and then changes to ERROR. Coolant temp is 16C and voltage 12.3v. Measuring blocks 74 show 0.53v 4.46v 0.531 and ERROR. Each time I switch on the ignition the same two codes come up, only the second of which can be erased. The CEL is off and the car is running fine now although I have only driven a couple of miles. I can only think GSF have supplied a duff EGR or I have a loom fault. Any way of checking this please?
