P38A Eas issue, helping a friend out.

Flossie · Oct 29, 2023

Took his 2001 for it's mot , it passed, but when he called back to mine just after it was leaning down on the rear left. Now, when I had mine mot'd the tester sent the whole car up until all 4 wheels were off the ramp and the eas responded as it should and all was well after but his has now this fault although he doesn't know if all 4 wheels were left dangling or not.
My first uneducated guess is that it was left dangling and a height sensor has thrown a wobbley maybe?
Anyway, I've got nanocom so could I somehow diagnose the issue with that? Popping down to his for an hour in the morning before he goes to work for a looksee.

If the wheels hung, a height sensor may have picked up dirt from a part of the track not normally used. Taking the arm off and moving the sensor through it's range a few time may clear it. I don't have a Nanocom but you should be able to see the actual readings from the sensors.
If they are old, another possibility is a leaking airbag after it was extended beyond the range it is normally at.

It does. Not always easy though if it's rusty.

No I'm not going to respond buy saying a good bush likes a bit of lube gently rubbing in.

Ooops just did

I've never seen an Mot done on anything other than a 4-post ramp?

It was. When I watched mine being done he used a jacking beam and kept lifting the whole car up, pausing until the eas caught up on extended height, ie- the axles were held by the fully extended dampers with all 4 wheels just off the ramp.
Had a look at my friends today and the offending side height sensor had a broken mounting tab allowing it to swivel a bit, temporarily fixed it in place and all is well again. I've read that the cheapy sensors are a bit hit and miss so we are going to see if a permanent repair to the existing one is possible.

The cheap sensors are definitely not very good. Don't ask me how I k know

Local MOT place here use a pit with a sliding hydraulic beam on rails to lift either front or back as required. Saves energy.

I seem to recall you had no issues with a cheapy one but that was a while back?

I forget exactly where my tester put the jacking beam but it must have been under the gearbox crossmember , the whole car sat level with all 4 wheels dangling. Made me nervous with it 6 foot up in the air.
