Excessive heating at temperatures below 0
°°°°
C
E46
Complaint:
At outside temperatures of less than 0
°
C, the vehicle is heated too strongly. The interior
temperature felt is much higher than that set.
Moreover, at these ambient temperatures, the blower speed is implausibly boosted in the
automatic air-conditioning program.
Cause:
Software error in the instrument cluster (versions 31.0 and 32.0).
Affected vehicles:
E46 with air-conditioning system or integrated automatic heating and air-conditioning
(options 530 or 534)
Manufacturing period: April 2002 to December 2002
Procedure:
Only recode the air-conditioner control unit in cases of customer complaint.
DIS CD "1st update to CD 32.0" or a later version is required.
Recoding the air-conditioner control unit will eliminate the software error in the instrument
cluster.
Note:
Recoding will not correct the faulty temperature status in the IHKR/IHKA.
Parts:
Do not replace any parts - this is not necessary.
Reimbursement:
Material and labour costs incurred can be claimed through the usual warranty channels
subject to current warranty terms.
