Wafted a very comfortable 190 odd miles towards the big smoke, no faults with engine, gearbox or suspension issues.
Wish the same could be said for the speedo, which is accurate by a GPS check up to 20mph, under reading by about 10mph from there to 65ish, then only about 2 to 3 mph slow.
 
Last night I bought some bits off the old black supercharged (titanic as i nicknamed it) that I sold to my school pal in Windsor as a donor vehicle not so long ago so thats a perfect excuse to drive my new one down for a long weekend away in February,
Transfer box, both diffs, propshafts, center fold out cupholder and steering column, and an air-conditioning pipe, intank pump and level senders as that seems to be an achilles heel for me (I can't remember the last time i bought a motor any motor and didnt need one within a month) and whatever else pops up,
Iv also ordered a rear entertainment remote and 2 rear earphones,
Then today on start up oil service due in 500 miles well everythings sat to do it so next week at somepoint

That don't sound right. Should be pretty accurate. There are some pots on the back of the instrument cluster that can act up and affect speedo readings. Maybe soneone tried tweaking them in the past?

I'm wondering if we've got some corrosion issues somewhere in the systems.
 
Wafted a comfortable almost 200 miles home again. So relaxing to drive.
Speedo error appears to be reducing with use, he had been laid up for about 6 weeks so guessing corrosion and damp are part of the issue.
Overall for 400 miles, including around 30 minutes stationary and cold start bits during maintenance we're happy with 21.3mpg too.

I had a bmw that had a crack in an abs sensor and when it rained the speedo would jump about as you describe
 
Did you get any other faults? Cruise control and eas raise/ lower happen at correct speed according to GPS, so only appears to be the actual speedo instrument. And no abs fault report.

On the bump stops again. On my way from BC to sunny Baja Mexico and roughly 100 miles north of San Francisco my left rear air spring developed a serious leak. Currently camped at the Ckear Lake State Park near the small town of Lockport. Hoping to get a replacement air spring installed some time in the next few days. Note sure I will continue with my trip. Too demoralized

Hope it goes smoothly for you, having just done Otto's rear air springs. They were both challenging, although had likely been in place for upwards of 12 years.

When my l322 td6 was killing an abs sensor i could get upto about 10mph then upto 70 before it would register a change in speed it was delayed and laggy more so when wet, they send speed from rear left sensor through the abs pump to the cluster,
I dont know how the p38 prosses wheel speed to the speedometer though im afraid, if you could get diagnostics on all 4 corners and see they read the same,
Possible a wheelbearings got play and upsetting the relucter ring reading,

You can sort this mate, have you managed to source one?
What's happened to the existing airbag? :)
