As we can’t tell what the fluid is from the seller, how can you be sure that it is compatible?
Personally, if it was me, I would just send it back. Their website says they accept returns.
Thanks a lot Marc, I tried 12889 - didnt seem to make much difference in diagbox. I was heartened to see it detected the VIN automatically. Did i get it right diaboxwise with that refill message ?GiveMeABreak wrote: 14 Jul 2024, 16:56 12889 is the RPO
Risk of clogging is not the additive level - that will generate a separate message. This means the filter has been unable to regenerate (despite multiple attempts by the engine ECU) likely as a result of stopping and starting or too short journeys that are preventing the exhaust gas temperatures from reaching the requirements before the filter can regenerate.
When this happens, it means you need to go for an uninterrupted drive of at least 40 MPH for 10-20 minutes (and I'd suggest you keep in 4th gear) to get the engine up to temp to allow a complete regeneration tot take place.
I put 3L into it - so not sure that qualifies as "refilling it" - it wasn't empty but after the 3L went in I still had nothing come out of the overflow hose. However thanks a lot for the help and the advice I'll get another 3L and put that in too - Is it correct that the tank's capacity is 4.5L as I read elsewhere here?GiveMeABreak wrote: 14 Jul 2024, 21:37 Yep, as long as you actually did refill the additive tank - if you didn't, then this will give inaccurate info to the engine ECU, so when the tank does actually need refilling you won't get a message and this can cause damage to the additive pump if it is allowed to dry-run. So now that you've actually reset the additive counter, I strongly suggest you top it up with a refill kit (unless you have topped it up), then you won't have to reset it again.
