Bosch does not have carbon cabin filters in stock, I have an Oxy-Pure type. This filter is not of the stock size and does not fit correctly in the Pollen Filter module, the length is shorter by an inch, but still I went a head and fixed it as I could not bear the stock filter.

I am unsure, if the size of the filter could be the reason; In general, the Bosch Pollen Filter does not allow any odors, but at times, it allows smoke odors from trucks and the filter itself gives strange smell during compressor cut off (Unsure why, may be due to dry air?).

Puneet(pk_del) from team-bhp is also using the Bosch Oxy-Pure filter, his filter is of the same size as stock one. We could ask him for a review.

I had called Bosch yesterday, you had provided the number for Ashok. He said they are out of stock on the filters and to give him a buzz next week.

I went on shopping spree this weekend and found activated carbon filter is shaped like a pentagon. Is this right or a spurious chinese ripoff ?

It will not serve its purpose since it will let in dust and smoke over its shoulders.

Bosch and other after market manufacturers like ZIP have Pollen Filter/AC filter for Dzire, I am certainly not sure if they would have active carbon filters in stock for DZire. Innova has an in stock active carbon filter from Bosch in Bosch car care.

That guy said, that the pentagon shaped stuff will fit my DZire. Since I have already tinkered with A/C of my car, I was able to call his bluff. Any idea where can I get it from a Bosch authorized auto spare parts shop in Hyderabad / Secunderabad ?

Yes, most likely all passenger Pollen Filter modules will be a square or rectangle, a misfit can potentially allow harmful gases and dust into the cabin, it can also permanently damage your vents. I do not know a place in hyd, if it is blr i could have helped you. For instance have a look at my Punto's pollen filter module.

Looks very similar in design with DZire. Any idea if you can find the evaporator coil from the fan end ? In DZire the coil is little higher than the lowest point in the plumbing. If its accessible in Punto, you are one lucky guy.

I have a question for Tech gurus/Experts,

I own a 2018 AWD Model RAV-4 with approx 15000 miles on board. I have a peculiar problem which is getting difficult for the mechanics at Toyota to troubleshoot. This is Happeneing for the last 8 months.

At one dealer, they told me to remove the dashboard and install a new blend door actuator, without even checking with the OBD scanner. Estimated cost 1000$

Another dealer came directly to the conclusion of a Kaput evaporator core and needs to be replaced. Estimated Cost 3000$

Then eventually, I went to a local car mechanic, who plugged an OBD scanner and restored the factory settings (Thats what he said) and all the vents started to throw cold air and happily I came back home thinking that the long pending issue is finally resolved. Note - All this time the car was on "running engine" at the local mechanic while he was troubleshooting, till I came back home. Paid around 100$ for scannning.

Next day while I cranked the engine and started moving for work, I noticed the same problem again, Hot air from passenger's vent and cold from driver's vent.

Now my question is what could be the probable cause and how I could trouble shoot or get it rectified ? Mind you car is very less used/having low mileage.

Mods- Please join this with the related thread, as I'm not able to find the similar issue.

Thanks in advance.

Does your car have separate climate controls for driver and passenger side? Since the ac is able to make cold air on the driver side, I would think there should not be an issue with compressor, refrigerant, evaporator etc. Either the climate control system is not able to sense the temperature on passenger side correctly or there is a problem with the blend door actuation / blockage in the ducts. The problem could be electrical as well where the climate control ECU / power connections to the blend door actuator / temperature sensor has a problem. This needs further diagnosis IMHO.

Thanks for your feedback. Yes, the car has separate climate control on either side. I have same thoughts about compressor, refrigerant, evaporator. However, for climate control system, blend door actuation or blockage of duct won’t be the case, because when OBD scanner was plugged and settings were restored, the AC system sprang back in action.
