For your situation, I've had great luck with the iCarsoft LR V3.0 for Land Rover/Jaguar. I'm a bit cautious when it comes to electronic parking brakes and air suspension, but this unit is solid and very reliable. It's specifically tailored for JLR protocols, so it hits those hidden modules your generic dongle missed. It fits right in your budget too! Honestly, I'm super satisfied with how it handles service resets without needing a laptop.

Hmm, I've had a different experience when it comes to the best value for money on the X351 chassis. While the iCarsoft is okay for basic resets, I'd actually suggest a different approach if you want deeper bidirectional control without spending a fortune. Respectfully, I'd consider the Foxwell NT530 Multi-System Scanner for Jaguar Land Rover instead.

In my experience, the Foxwell is much better at handling the active suspension calibration and electronic parking brake (EPB) service mode on the XJ than the iCarsoft units. It supports full Jaguar-specific protocol access and actually lets you code some modules, which is a lifesaver for DIY maintenance. Another solid contender if you're comfortable using a smartphone is the Autel MaxiAP AP200 Obd2 Scanner. It's super cheap but surprisingly powerful for JLR-specific diagnostics. Honestly, the Foxwell is the sweet spot for your $200 budget. It feels way more robust for actual shop-level work. What kind of suspension codes are you seeing now?

Seconding the recommendation above regarding the Foxwell. I’ve been there with my X351 and, honestly, it’s frustrating when standard tools fail. Safety-first, right? I've had issues with cheaper units failing during an EPB service, which is terrifying. If you want something rock-solid for air suspension calibration without the JLR SDD headache, look at the Autel MaxiCheck MX808S-TS. It’s slightly over $200 but covers bidirectional tasks safely.

TL;DR: Foxwell NT530 for Jaguar Land Rover is great, but Autel MaxiCheck MX808S-TS offers better long-term safety for critical modules.

In my experience, I've dealt with the same headaches on my X351. I tried a few cheap dongles that were totally useless for the air suspension. Honestly, I was pretty disappointed with some of the more expensive generic ones too—they just couldn't talk to the Jaguar modules.

For your situation, I would suggest the iCarsoft LR V3.0 for Land Rover/Jaguar. I've used it for electronic parking brake (EPB) releases and resetting the service light, and it actually pulls those hidden proprietary codes. Another solid pick around that price is the Foxwell NT530 with Jaguar Software. It's a bit slower, but the bi-directional support is decent for the money. Hope this helps!
