Reviews of Bosch parts For Business

I installed the starter, which was apparently the upgrade and Bosch has since reverted back to the "old style" with the support dowel. Everything starting-wise is working great

Bosch Icons. They will last a year and a half or so if you're in a warm weather climate.

The Bosch Icons are fantastic and worth the price for me. I live in South Florida and we get a ton of rain - I am on the same pair from 2020. I clean/wipe them at every car wash interval. Visibility is great AND my wipers last a long time.

Stick with Bosch if possible, get the autostick (SR17X) starter and eliminate bushing issues.

Bosch Icons are best.

I’ve had Bosch Ion blades (the same pair) for years now and they’re still super awesome. I’ve never had wiper blades for quiet.

Bosch ICON tested the best after a year of exposure to the elements.

I tried to correct with a new and proper group size battery - it had an OE 140A Bosch alternator and starter with a 2016 El Cheapo battery that was one group size too small so I replaced the H5 with a new H6 group and all was good for a few days... I also replaced the starter just because I like to spend $ and wanted a clean slate as this a vehicle I intend to keep and drive daily as needed. The new battery/starter work great but I noticed right away that the voltage while at idle was now almost a full 2 volts lower than before changing any of the afore mentioned parts. I have a P3 dash vent gage that reads to 0.1V and I use a VOM plus VCDS so I know the P3 reads OK. Before changing any parts the P3 read 13.5 to 14.4 volts steady depending upon what accessories were on. After the H6 battery the P3 read 11.5 to 12.5 volts under the same driving conditions. I tried to get the OE alternator bench tested but that did not work so I just went with a new reman Bosch unit. No change in voltage with the new alt... So this past weekend the motor fired up just fine and the dash vent P3 gage display was 12.5V but while driving around town running errands the voltage kept dropping all the way down to 9.0V which caused the DSG to lock and basically leave me stranded miles from home. I will try to get the entire electrical system load tested this weekend but for now I just keep a tender on the batter at night as I do not drive much during the week nor do I commute. The tender keeps the battery at 13.0V reliably.

On my '93 240, I used a 740 external regulator Bocsh alternator...100amps...the problem is is that the voltage regulator takes a dump, which leads to people replacing the entire unit (like me years ago).

Never use the Bosch ones for the E46s. Just not working right
