Peugeot Boxer reverse judder - thank you Peugeot
Credit where it's due. Peugeot seem to have sorted things out for us. I took our Boxer-based motorhome into our local Peugeot dealer before Christmas and was told that yes, it juddered but no, there was nothing that they could do because Peugeot were no longer authorising replacement of engine mounts, engine management upgrades or replacement of reverse gears. Not happy with this, I got onto Peugeot Customer Care who were extremely helpful. Apparently, the dealer had not bothered to check with Peugeot but had given a stock answer. Peugeot immediately authorised replacement of reverse gear and the van went in for the work.
A few days later, the dealer reported that they were unable to separate the gear from the shaft in the gearbox and that Peugeot had therefore ordered replacement of the entire gearbox to get us back on the road quickly. The bill (which we didn't have to pay, as the warranty covered it): £5500, including gearbox, new flywheel, new clutch etc. etc.
The result, four months on: the judder has gone. Admittedly, I still think that reverse gear is too high a ratio but the judder and fear of resulting clutch problems have gone.
Thank you Peugeot. I might, before this resolution, have thought twice about buying a Peugeot-based motorhome again but they do seem to sort you out, even if the dealer is not very on the ball.
Aside: on the first visit, the dealer had resealed the scuttle panel to stop water getting into the engine - one of the other things I'd booked it in for - but, after my conversation with Peugeot, the dealer then fitted the proper engine cover. It does seem that you need to know what needs doing, when talking to a dealer. Thanks to you people for providing very useful information.
