Hi all! We have been experiencing an issue on site where threads have been missing the latest postings. The platform host Vanilla are working on this issue. A workaround that has been used by some is to navigate back from 1 to 10+ pages to re-sync the thread and this will then show the latest posts. Thanks, Mike.

    Strenght could be the pollen filter.... About 10 to 20 quid. As for the heat. Is the correct amount of coolant in the system ?

    Ok taking crystal ball in hand! Sludgy coolant oil getting in, common for oil coolers to leak on both petrols and diesels, may have been repaired previously or may be at fault now, oil/sludge causes poor flow through heater matrix therefore poor heat, if faulty now replace cooler and flush system until clear, if previously problem flush system and heat should return.

    Whatever about oil in the coolant, the possibility of coolant in the oil would have me far more worried!
