Following work on the front end chassis over the weekend I have the following collection of errors. On the way home of a half hour drive, about 5 minutes from home, these came up. They also come up every time the ignition goes on.

What’s the consensus:

1. Lee’s battery is on its way out - it’s coincidence

2. Lee’s ham-fisted approach has probably unalived a wheel speed sensor

3. Changing the rear drop links, front droplinks and lower arms (including loosening the subframe and now making the car pull left unless the steering is 30degrees right) probably means an ADAS recalibration is needed

Booked in for a few things end of the month (oil service, dsg service, ruddy top mounts, front arb) then straight for 4wa after. Question is, do I need to do anything else as well?

Also tested the battery and was pretty decent SOH and SOC so that doesn’t flag immediately but I could be being naive on that…

Thoughts…?

Crikey.....it's all broken.

Have u done a wheel alignment after mucking around with ur suspension?

That's rule #1.

As for the other errors - makes no sense, given u checked ur battery n it seems good.

4wa is booked - couldn’t schedule doing the work and getting the alignment done straight after. Minimal miles so I’m not overly worried about it as it’s a known.

But it’s whether there’s a healthy chance that the midalignment would also trigger any or all of these by throwing out ADAS is what I’m curious about. Or whether it’s perhaps a wheel speed sensor as well and it’s multiple causes.

ACC doesn’t work, nor does auto main beam (crystal matrix).

That with the lane assist and dynamic lighting I could believe is ADAS, but the tyre pressure indicator, ESP, Autohold and hill start assist definitely point to a wheel sensor.

Rear traffic alert doesn’t really fit into any of those categories though.

Did u check the leveling sensors on the front LCAs?

Usually when u remove or lower the LCA, u need to disconnect the leveling sensors so they don't snap or break.

If they do break, or the wrong way round, the suspension (DCC), headlights, ABS and steering will b upset.

There r two on each front LCA, and one on the rear left arm.

Looks like this......

Rear...

Yep, good shout. Had watched lots of YouTube vids and was sensitive to that. Rear didn’t need touching as we changed the droplinks in situ.

Front were unbolted and kept out the way then bolted back in, in the right holes. I can see the headlights self-level when I start the car so figure they’re working and happy too.

Hopefully it's all sorted soon and u can get back to enjoying the car again.

Cheers buddy - will update when I find out more.
