Tach municipality, once again the little one from my daughter……Daughter has been coming to dad for weeks and says my car often shows coolant level too low. Ok, so once filled up and good, externally nothing to recognize. No water loss in the engine, ÖL even without entry. So first filled up. Result after 14 days again over 0.5 ltr away…… so sometimes a little bit stuttered and came on the topic AGR cooler. Today at the friendly ….he wants to check however only for so much how the AGR cooler costs me…325 EUR. When I learned cart clamper … there were not such great things yet. Ergo I might need some tips…..redeem was removed from the temperature sensor – if this fully Russ everything ok if clean then AGR cooler defective. Also some tips where the AGR cooler sits and how this is removed. Thank you ! Grs TOSCH
