Hi Danny and welcome on board !

- have you got any chance to scan the ECU for possible error(s) ?
- You mentionned crank sensor, how about the timing one ?
- Is the temp Indicator showing correct values ?
- Is the car running ok once started ?

First would be to spend some pounds on MES and a ELM327 reader, it will help solving your issue and the potential future ones …

BRs, Bernie

Then it's probably the culprit, the Bottom sensor you already replaced will compute the TDC by detecting when all 4 pistons are in mid travel, while the timing sensor will detect WHICH cylinder is in its compression stroke (thus injection & ignition)

Here are some stuff to help locate it … We're looking for K047 and #13

Sounds like some improvement no ?
What is your level about checking electrical devices such as sensors ?
When replacing the RPM/TDC sensor (crankshaft) you HAVE TO run the learning procedure (see alttached) !

Always worth getting a copy of MES (https://www.multiecuscan.net/) and an decent OBD2 cable to check codes and engine running information
