If your codes are active, deal with the P0947 TCM low voltage first - could cause all the other codes. Good Luck, Iz

I'm not that familiar with the 451, but if I remembered correctly, some of the them has issues with the clutch plate binding to transmission input shaft. When the ECM sees rpm on the input shaft when the clutch is supposed to be engaged, it will prevent starting and sometimes have very rough/weird shifts. Good Luck, Iz

If you buy a used SAM, then you’ll have to use special tools to “clone” it. Otherwise you’ll have odometer mismatch and possibly programming issues. if you buy new from the dealership, then it’s just expensive.

Misfiring codes for our diesel 450 in my experience is almost always related to intake valves. Sometimes the lifter is seizing or broken (wouldn't be intermittent if broken), other times is worn or burnt intake valves causing compression lost. Good luck! Iz

Best of luck!

I’ve seen this before on a smart that I had worked on. Ended up being the SAM - the guy had corrosion due to a water leak at the windshield. Good Luck

We're meeting on Sat in St. Albert Triple-O at 5pm.

The clutch actuator position may trip the P0805, but it’s unclear at this point. You should be able to push the actuator rod all the way back in before installation. Make sure the clutch fork pivot point where the rod goes in is not worn or punched through. You will not be able to push the fork with your fingers - it’s basically the spring tension that keeps the clutch engaged. If you’ve already changed the clutch actuator, then you’ll need to check your wires/harnesses. You'll also need a scanner that can do clutch/drag point calibration similar to the STAR. I have an Autel Mk906 pro that can do that. I’m sure there are plenty of other scanners out there that can do it as well.

Old topic, also discovered that if the cluster stays on, it will code the FOB (lock/unlock) but the immobilizer will stay locked. This usually happens when someone messes with the fuse clips on the side of the SAM - no plugged back in correctly.

Old topic, but I finally came across a Car2Go! STAR basically says there are ways to code keys. 1) Reinitialize SAM setup, or 2) get the Car2Go password. The Car2Go SAM software is different than the normal one. Not sure if the hardware is different. Another challenge with this one that I’m working on is that the owner was only given the spare and not master key. Will report back once I have it figured out. Iz

If you are getting circuit codes, then the basic thing to do is the check your wiring. They may appear okay on the outside, but internally wires can be broken due to vibrations. Disconnect your ECM and test each circuit going to the actuator. Load test your power and ground circuits to start. Evilution.co.uk will have some sort of wiring schematics to help. Good luck, Izzy

Some pics of the intake valves? Normally the wear is on the valve and not the seat. Maybe rebuildable. I don’t usually see issues with the short block.

Most likely worn intake valves.

I have one, but I imagine that shipping something that size will cost an arm and leg. Let me know if you’re not able to source one locally.

@ZCMK123 The OEM connector is readily available. Plug and Play. I know guys that are running the Amazon 7” fan and those draw about 80w. This quad fan setup only does around 67.2w max - should have no problem. I have a scangauge2. If you want one, @Avenge95 has one for sale I think. @MikeT Today’s ambient was 32-35C. Going at 110kph, I had steady 103C coolant and IAT 50C. It peaked 108C coolant and IAT at 59C (highest recorded yet) going up hill with A/c in max. @MikeT maybe I’ll finally catch up to your mileage? I’m at 178k. Thought about selling it to get an Abarth 500, but the thing with Smart cars is most people won’t appreciate the Brabus C1. I won’t sell to someone that’ll trash it (which is basically everyone in AB). Only time will tell if the server fans will hold up to road abuse and moisture. I might also add a controller so that at idle the fans wont be at full power to help with the noise.
