My (56 plate) Altea FR TDI170 has developed an annoying quirk recently; it normally idles at 850rpm ish within a minute or two of starting and thereafter; but if I'm doing a fair bit of low speed driving around town, it soon decides it would rather idle at 1000rpm. As soon as I get out of town, it quickly reverts to 850rpm. Any suggestions?
