[quote=""X5Sport""]Mine too, but the chemical tank control has seized up. Looks like repairing it might be a bit of fun even with the exploded diagrams. Spares are about but it's hard to tell exactly which bits are needed (at present). Might have to take it to bits and some parts are expensive. Certainly needs new valves etc, hence looking for a newer one in case the repairs get silly.[/quote]

imo not really worth repairing those.. btw i'm still wonderin whether the underside needs cleanin.. too expensive and low down the list right now

The expense bit was bothering me too. The unit is worth nowt being 17 years old, and although spares are available, they aren't cheap.. Looks like nearly £100 for the housing and valvegear and I'd rather put that toward a replacement. If you don't keep your cars for any length of time then worrying about the underside is rightly lower down the list, but it might help save corroded brake lines etc which have been affecting some folks, and is higher up the list for those like me who tend to hang on to their cars. It's likely now that I'll keep mine fore 6-7 years, maybe more (reliability & costs permitting).
