down at the front P38 following garage trip

Hi guys, I live in France and have a P38 diesel. My car went to the local garage (LR too far away and is Ford anyway!) yesterday for an oil change and a replacement door handle and since then the front doesn't lift properly and th dash height indicator keeps flashing. There's no alert message. could the garage have created a problem when they had it on the ramp or is it likely to be the front air springs ( I replaced the rear ones last year)
 
Was it a Drive on 4 wheel lift ramp or one of those 4 point chassis lift ramps which leaves the wheels dangling??

Whereabouts in France are you located, there maybe a member local to you who can help out...?

First thing to do is check the compressor is giving output...follows Wammers How To in the How To section for checking the compressor.

If the compressor is creating good air pressure, next thing is to check the condition of the front bags....
 
Thanks, I'll do as you suggest. I assumed the compressor is OK if it lifts the rear but perhaps not. Seems odd that it should have happened whilst in the garage too. I live near the coast between Caen and Cherbourg
 
Oh yes and th
e garage confirms it was a 'dangler'
Hmmmmm....Range Rovers don't really like dangler lifts...

What can happen is as the axles drop, this moves the height sensors to a position that is rarely used and can drag crap over the internal wiper....

The height sensor is basically a wound coil and a wiper arm...as the wiper arm moves over the coil, the resistance the wiper picks up changes....if the wiper moves to a point on the coil that is not normally used and is dirty (like when the axles drop) it can interupt the height signal....causing issues.

If the rear rises and the front struggles....the system is designed to raise the rear first, then the front, then rear then front again, this is to stop dazzling the oncoming traffic, if the compressor is tired, it will not have enough ummph to fill the tank to raise the rear, but as the tank level drops, the compressor then struggles to fill the tank and raise the front...

Try the Wammers compressor check first - No Air Pressure, No EAS!

If that checks out....it could be a split bag on the front....Dangler Lifts stretch the Air Bag to full extents and this can potentially reveal splits in the bag and allow the to open!

EDIT: Your location is a bit further away from who I thought could help, he is further south near Poiters.....still give Datatek a PM, he can supply the EAS Diagnostic cable and Software for £11+postage or whatever that is in that funny foreighn currency you guys use :D

If the airbags are old and the lift fully extended them, I would bet you have a split in one or both of the bags.
